Global Illumination Across Industries SIGGRAPH 2010 Course Thursday, 29 July | 2:00 PM - 5:15 PM | Room 502 A (hover mouse over name for presenter info) Abstract Global-illumination (GI) computation has been the subject of intense research in computer graphics for many years, but it has only recently been extensively used in practical applications. Major industries, such as videogame and film prod

The Cornell Box Cornell University Program of Computer Graphics The Cornell Program of Computer Graphics has become best known for its research on physically based rendering. We believe that computer graphics simulations will never become predictive of reality unless we correctly model the physics of light reflection and light energy propagation within physical environments. The Cornell Box experi

The ISO standard for measuring resolution of “electronic still imaging”" cameras is 12233, available only from the International Standards Organization for only 116 Swiss Francs (about $US93 as of this writing) and under copyright protection. But the design of the test chart seems not to be protected; its description has been available on the Web in an Excel spreadsheet. I have semi-manually conve
Cornell Box Data Cornell University Program of Computer Graphics Photographic Images We have made high-quality pictures of the Cornell box in its current configuration. The liquid-cooled Photometrics PXL1300L CCD camera has a precision of 12 bits. We used 7 narrow-band filters to get a coarse sampling across the visible spectrum. Dark current has been subtracted from the images, and flat-field cor
RGBE Image Format Specifications Cornell University Program of Computer Graphics RGBE is an image format invented by Greg Ward Larson. It stores pixels as one byte RGB (red, green, and blue) values with a one byte shared exponent. Thus it store four bytes per pixel. RGBE's biggest advantage is that it allows pixels to have the extended range and precision of floating point values. Often when we ge
Fast, minimum storage ray-triangle intersection. Tomas Möller and Ben Trumbore. Journal of Graphics Tools, 2(1):21--28, 1997. We present a clean algorithm for determining whether a ray intersects a triangle. The algorithm translates the origin of the ray and then changes the base to yield a vector (t u v)T, where t is the distance to the plane in which the triangle lies and (u,v) represents the co
